Electrostatics Question 115
Question: A parallel plate capacitor has an electric field of $ 10^{5}V/m $ between the plates. If the charge on the capacitor plate is $ 1\mu C $ , the force on each capacitor plate is [Orissa JEE 2002]
Options:
A) $ 0.5N $
B) $ 0.05N $
C) $ 0.005N $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ F=\frac{CV^{2}}{2d}=\frac{Q\times E}{2}=\frac{{{10}^{-6}}\times 10^{5}}{2}=0.05N $
